From here, we look inward to biochemistry and biology. To truly understand biochemistry, scientists study and see the unseen by studying the chemistry of biological processes. This science, along with biophysics, aims to bring a better understanding of how bodies work – from how we turn food into energy to how nerve impulses transmit. analytic geometry, branch of geometry in which points are represented with respect to a coordinate system, such as Cartesian coordinates, and in which the approach to geometric problems is primarily algebraic. Its most mon application is in the representation of equations involving two or three variables as curves in two or three dimensions or surfaces in three dimensions. For example, the linear equation ax+by+c=0 represents a straight line in thexyplane, and the linear equation ax+by+cz+d=0 represents a plane in space, where a, b,。 the harnessing of accidents that occurred during the process of painting。 the use of huge canvases。s first oneman show in 1948 established him as a highly influential artist.

The choline is then available for reuptake into the nerve terminal. These same principles apply to cholinergic transmission at sites other than neuromuscular junctions, although the structure of the synapses differs. In the autonomic nervous system these include nervetonerve synapses at the relay stations (ganglia) in both the sympathetic and the parasympathetic divisions, and the endings of parasympathetic nerve fibres on nonvoluntary (smooth) muscle, the heart, and glandular cells。 He is no richer than his brother. 他與他弟弟一樣不富有。例如： She runs no faster than her sister. 她與她妹妹一樣跑不快。 Iron is more useful than any other metals. 鐵比其他任何金屬更有作用。做這種句子時有一點(diǎn)要特別注意 別忘了常在比較狀語中用 any ,other , else 類的字眼，以將比較主體排除在比較對象以外，因為自己不可以與自己相比較。 8) 用比較級的形式表達(dá)最高級的意思。 There is more than one solution to the problem. 這個問題的解決辦法不止一個。所謂 沒有比較對象的比較結(jié)構(gòu)不是指省略而言，而是指并非真正的比較。s performance. 他對足球隊的表現(xiàn)越來越不滿意了。 When winter is ing , it gets colder and colder .冬天來臨之際，天越來越冷了。例如： The harder you work at your study, the better academic records you will have. 你學(xué)習(xí)越努力，你的成績就越好。和 比較級 + and + 比較級 。 She came even earlier than I asked (him to). 她來得 甚至比我叫她來的時間還要早。 You39。 5) 在比較級 + than的結(jié)構(gòu)前可以加上某些副詞類和表示倍數(shù)的詞，以對其進(jìn)行修飾，如： far（遠(yuǎn)）， even（甚至），much（許多）， still（更，還）， a lot（許多 ）， a little / bit（一點(diǎn)）， rather（相當(dāng)?shù)兀?slightly（略微），not any（不再）， three times … （三倍、 …… ），等等。例如： They worked even harder than they promised. 他們工作得比他們答應(yīng)的還要賣力。 4）不同級的比較主要用表示于人與人、 事物與事物之間不同之處的比較，其意義為 A 比 B更（怎么樣）一些 。例如： She spread as much butter on her bread as Jane usually does. 她在面包上涂的黃油與瓊通常涂的一樣多。t been quite so unlucky as she pretends. 她還沒有象她常裝出的那樣不幸。 Cast iron is almost as useful as steel. 鑄鐵差不多與鋼一樣有作用。例 如： Asia is four tomes as large as Europe. 亞洲有歐洲的四倍大（亞洲比歐洲大三倍）。t speak English as fast as a native speaker. 我說英文沒有以英語為母語的人說得快。 It is not so hot as yesterday. 今天不象昨天那么熱。 His bedroom is not as neat as his sister39。例如： My parcel is as heavy as yours . 我的包裹與他的一樣沉。 1） 同級比較中有兩種情況： 表示雙方情況 一模一樣 ，用 as + 原級 + as的結(jié)構(gòu)； 表示雙方情況 不（那么）一樣 ，用 not so / as + 原級 + as的結(jié)構(gòu)。 4) 要注意幾種比較級的特 殊句型，如： the + 比較級 … ， the + 比較級 …… ，意思是 越 …… 越 …… ；以及 比較級 + and + 比較級 意思是 越來越 … ，等。另外 no more …than 意思是 A和B一樣不 …… 。 2)比較級 + than引導(dǎo)不同級的比較。 第 36 單元 在本單元中，復(fù)習(xí)在 units3135 中的語言知識和技能，并進(jìn)行自測。 第 35 單元 在本單元中，你將學(xué)習(xí)了解太空，星球以及太空旅游方面的內(nèi)容。 第 34 單元 在本單元中，你將學(xué)習(xí)了解與不同尋常的旅游和冒險活動相關(guān)的內(nèi)容。 第 33 單元 在本單元中，你將學(xué)習(xí)了解旅游和探險方面的內(nèi)容。 第 32 單元 在本單元中，你將學(xué)習(xí)了解空中旅行的過去、現(xiàn)在和未來。 第 31 單元 在本單元中，你將學(xué)習(xí)了解旅游度假和旅游對環(huán)境的影響的內(nèi)容。 every只能作定語； each 則可以作主語、賓語、定語和同位語。 Her clothes were all wet.（作副詞） 她的衣服全濕了。另外， all 指不可數(shù)的事物時還可以作表語；有時還可作副詞用，例如： This is all he knew about it. （作表語） 這就是他了解有關(guān)這件事的一切。t lose courage. （說話人不希望假設(shè)的情況發(fā)生）即使他們?nèi)f一失敗，他們也不會泄氣。 與未來事實相違背 If I should have a chance to try it, I would do it in another way. （假設(shè)的情況不大可能發(fā)生）要是我有機(jī)會試一試，我會用另一種方法做的。t been caught by something, I would have e to your party yesterday.(事實是：我昨天被某些事纏住了 ) 我昨天要不是被些事纏住了，我就會去參加你們的聚會了。 第 30 單元 在本單元中，復(fù)習(xí)在 units2529 中的語言知識和技能，并進(jìn)行自測。 第 29 單元 在本單元中，你將學(xué)習(xí)了解有關(guān)未來科技發(fā)展方面的內(nèi)容。 第 28 單元 在本單元中，你將學(xué)習(xí)了解有關(guān)科技進(jìn)步方面的內(nèi)容。 第 27 單元 在本單元中，你將學(xué)習(xí)了解互聯(lián)網(wǎng)對人們?nèi)粘Ｉ畹挠绊憽? 第 26 單元 在本單元中，你將 學(xué)習(xí)了解電信技術(shù)，尤其是移動電話和家用計算機(jī)的快速增長對人們生活產(chǎn)生的影響。 第 25 單元 在本單元中，你將學(xué)習(xí)了解新技術(shù)對日常工作產(chǎn)生的影響。 We happened to have e across the article once .我們碰巧有
